Super Loop Antenna
The Superloop is the 30' length of ladderline hanging down from the center insulator. This length has been tuned so that appears to be a open circuit stub on 40 meters; thus the antenna becomes two full wave wires at 40 meters and is commonly referred to as the Bi Square antenna

The 40/30 Pyramid
I have something here that I believe is new. If it isn't then that's ok ,I don't use EZNEC or read antenna articles much. I like to innovate. This antenna is an innovation. I have read about a sloping two band Delta loop but it used two feed lines mine uses one. It is called the 40/30 pyramid

Two element parasitic delta loop array
Ladder line fed loops perform well.K4QKY hasbeen using large multi band ladder line fed loop antennas with good success for many years




Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band

Rx antennas 4Square Rx Vertical Array

Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m

Atu balanced feeder antenna system

Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
